Please carefully select your division. For seniors and women, your division is determined by your age as of February 6, 2026. For participants in the men's and open divisions, you are required to make all first deliveries in all frames in the orientation you register for. For example, a bowler signing up as right-handed will not be allowed to throw a backup ball on the left side of the lane on any strike attempts. If a men's, women's, or senior division is full, you can sign up in an Open division if space is available.
